Description

The present invention generally relates to inhibitors of glutaminyl peptide cyclotransferase, as well as rheumatoid arthritis, atherosclerosis, restenosis, pulmonary fibrosis, liver fibrosis, kidney fibrosis, pancreatitis, mild cognitive impairment, Alzheimer's disease, down Neurodegeneration in syndrome, familial British dementia, familial Danish dementia, neuropathic pain, graft rejection / graft failure / graft vascular disorder, hypertension, HIV infection / AIDS, pregnancy toxemia, cancer / Angioendothelioma growth, tuberous sclerosis,
And its use for the treatment and / or prevention of a disease or disorder selected from the group consisting of gastric carcinoma.

Furthermore, the present invention belongs to diagnostic kits and methods based on the use of glutaminyl cyclase inhibitors.

Glutaminyl cyclase (QC, EC 2.3.2.5) is an intramolecular cyclization of N-terminal glutamyl residue to pyroglutamic acid (5-oxo-proline, pGlu *) under the release of ammonia, and under the release of water. Catalyze the intramolecular cyclization of N-terminal glutamyl residue to pyroglutamic acid.

QC was first isolated from the latex of tropical plant papaya in 1963 by Messer (
Messer, M. 1963 Nature 4874, 1299). Twenty-four years later, the corresponding enzyme activity was found in the animal pituitary (Busby, WHJ et al., 1987 J Biol Chem 262, 8532-8536; Fischer,
WH and Spiess, J. 1987 Proc Natl Acad Sci USA 84, 3628-3632). For mammalian QC, QC conversion of Gln to pGlu could be demonstrated for TRH and GnRH precursors (Busby, WHJ et al., 1987 J Biol Chem 262, 8532-8536; Fischer, W
H. and Spiess, J. 1987 Proc Natl Acad Sci USA 84, 3628-3632). in addition,
Early localization experiments with QC revealed co-localization with its putative catalytic product in the bovine hypothalamus-pituitary tract, which further improves function in the suggested peptide hormone maturation (Bockers, TM et al., 1995 J Neuroendocrinol 7, 445-453). In contrast, plant Q
The physiological function of C is not very clear. In the case of C. papaya-derived enzymes, a role in plant defense against pathogenic microorganisms was suggested (El Moussaoui, A. et al., 2001 Cell Mol Li
fe Sci 58, 556-570). A putative QC from other plants has recently been identified by sequence comparison (Dahl, SW et al., 2000 Protein Expr Purif 20, 27-36). However, the physiological functions of these enzymes are still ambiguous.

Known QCs from plants and animals showed strict specificity for L-glutamine at the N-terminal position of the substrate, and their kinetic behavior was found to follow the Michaelis-Menten equation (Pohl, T. et al., 1991 Proc Natl Acad Sci USA 88, 10059-10063; Consalv
o, AP et al., 1988 Anal Biochem 175, 131-138; Gololobov, MY et al., 1996.
Biol Chem Hoppe Seyler 377, 395-398). However, a comparison of the primary structure of QC from C. papaya with that of a highly conserved QC from mammals revealed no sequence homology (Dahl, SW et al. (2000) Protein Expr Purif 20, 27-36). Plant QC appears to belong to a new enzyme family (Dahl, SW et al. (2000) Protein
Expr Purif 20, 27-36), mammalian QC was found to have clear sequence homology to bacterial aminopeptidases (Bateman, RC et al., 2001 Biochemistry 40, 11
246-11250), leading to the conclusion that plant and animal-derived QCs have different evolutionary origins.

EP 02 011 349.4 discloses a polynucleotide encoding insect glutaminyl cyclase, as well as the polypeptide encoded thereby. This application further provides a host cell comprising an expression vector comprising a polynucleotide of the invention. Host cells containing the isolated polypeptide and insect QC are useful in methods of screening for agents that reduce glutaminyl cyclase activity. Such drugs are described as being useful as insecticides.

Chemotactic cytokines (chemokines) are proteins that attract and activate leukocytes and are thought to play a fundamental role in inflammation. Chemokines are divided into four groups classified according to the appearance of the N-terminal cysteine residue ("C"-;"CC"-;"CXC"-, and "CX3C"
-Chemokine). “CXC” -chemokines act preferentially on neutrophils. In contrast,
“CC” -chemokines preferentially attract monocytes to the site of inflammation. Monocyte infiltration is thought to be an important event in a number of disease states (Gerard, C. and Rollins, BJ)
(2001) Nat. Immunol 2, 108-115; Bhatia, M. et al. (2005) Pancreatology. 5, 132
-144; Kitamoto, S., Egashira K. and Takeshita, A. (2003) J Pharmacol Sci. 9
1, 192-196). The MCP family, as a family of chemokines, consists of four members (MCP-1-4), showing preference for attracting monocytes but showing differences in their potential (Luini, W. et al. (1994) Cytokine 6, 28-31; Uguccioni, M. et al., (1
995) Eur J Immunol 25, 64-68). The following shows both the MCP-1 to 4 cDNA as well as the amino acid sequence:

Numerous studies have been published, particularly atherosclerosis (Gu, L. et al. (1998) Mol. Cell 2
275-281; Gosling, J. et al. (1999) J Clin. Invest 103, 773-778); Rheumatoid arthritis (Gong, JH et al. (1997) J Exp. Med 186, 131-137; Ogata. , H. et al. (19
97) J Pathol. 182, 106-114); Pancreatitis (Bhatia, M. et al. (2005) Am. J Physiol Gast
rointest.Liver Physiol 288, G1259-G1265); Alzheimer's disease (Yamamoto M. et al. (2005) Am. J Pathol. 166, 1475-1485); Pulmonary fibrosis (Inoshima, I. et al. (2004) Am
J Physiol Lung Cell Mol. Physiol 286, L1038-L1044); kidney fibrosis (Wada, T. et al. (2004) J Am. Soc. Nephrol. 15, 940-948), and graft rejection (Saiura, A. et al. (2004) Arterioscler. Thromb. Vasc. Biol. 24 1886-1890) has been emphasized the important role of MCP-1. Furthermore, MCP-1 is also used in pregnancy toxemias (Katabuchi, H. et al. (2003) Med Electron Microsc. 36, 253-262) and tumor onset (Ohta, M. et al. (2
003) Int. J Oncol. 22, 773-778; Li, S. et al. (2005) J Exp. Med 202, 617-624)
Neuropathic pain (White, FA et al. (2005) Proc. Natl. Acad. Sci. USA), and AIDS (Park, IW, Wang, JF and Groopman, JE (2001) Blood 97, 352-358; C
oll, B. et al. (2006) Cytokine 34, 51-55).

The mature form of human and rodent MCP-1 is post-translationally modified by glutaminyl cyclase (QC) to have an N-terminal pyroglutamyl (pGlu) residue. MCP-1's chemotaxis performance is
To be mediated by its N-terminus (Van Damme, J. et al. (1999) Chem Immunol 72, 4
2-56), N-terminal pGlu modification results in protein resistance to N-terminal degradation by aminopeptidases, which is important. Artificial elongation or degradation causes loss of function, but MCP-1 still binds to its receptor (CCR2) (Proost, P. et al. (1998) J Imm
unol 160, 4034-4041; Zhang, YJ et al., 1994, J Biol. Chem 269, 15918-15924;
Masure, S. et al., 1995 J Interferon Cytokine Res. 15, 955-963; Hemmerich, S. et al. (1999) Biochemistry 38, 13013-13025).

Because of the major role of MCP-1 in many disease states, anti-MCP-1 strategies are required. Therefore, small orally available compounds that inhibit the action of MCP-1 are promising candidates for drug development. Inhibitors of glutaminyl cyclase are pGlu at the N-terminus of MCP-1.
-A small orally available compound that targets an important process of formation. (Cynis,
H. et al. (2006) Biochim. Biophys. Acta 1764, 1618-1625; Buchholz, M. et al. (
2006) J Med Chem 49, 664-677). As a result, the N-terminus of MCP-1 resulting from QC inhibition is not protected by pGlu-residues. Instead, the N-terminus is a dipeptidyl peptidase such as dipeptidyl peptidase 4, and fibroblast activation protein (FAP, Seprase
) Have a glutamine-proline motif that is abundant on the endothelium and in the blood circulation. This cleavage results in the formation of MCP-1 with the N-terminus truncated. These molecules then develop antagonism at the CCR2 receptor, thus effectively inhibiting the disease state associated with monocytes.

Atherosclerotic lesions that restrict or prevent coronary blood flow are a major cause of mortality associated with ischemic heart disease, resulting in deaths of 500,000 to 600,000 people each year. Percutaneous coronary angioplasty (PTCA) to open occluded arteries was established in 1996 in over 550,000 patients in the United States and 9 worldwide.
Performed in 45,000+ patients (Lemaitre et al., 1996). The main limitation of this technology is PTCA
The problem of vascular closure after PTCA, both immediately after (acute occlusion) and long-term (restenosis):
30% partially lesioned patients and 50% chronic total lesioned patients will progress to restenosis after angioplasty. In addition, restenosis is a significant problem in patients undergoing saphenous vein bypass grafts. A number of factors appear to be involved in the mechanism of acute occlusion and blood vessels with resulting arterial closure and / or platelet deposition along the damaged length of newly opened blood vessels It can be caused by recoil and subsequent fibrin / red blood cell thrombus formation.

Restenosis after angioplasty is a slower process, accompanied by the release of cell-derived growth factor from adherent platelets, and subsequent inflammatory cells that contribute to intimal smooth muscle cell proliferation and vascular hyperplasia Involved in the early, but not critical, formation of thrombosis with local infiltration. It is important to note that multiple processes of these thrombosis, cell proliferation, cell migration, and inflammation each seem to contribute to the restenosis process.

In the United States, a 30-50% restenosis rate is interpreted as 120,000 to 200,000 US patients at risk from restenosis. Only 80% of these patients choose repeated angioplasty (the remaining 20% choose coronary artery bypass grafting), which adds to the cost of coronary artery bypass grafting for the remaining 20% What is the total cost for restenosis treatment easily in the US?
It will be a billion dollars. Thus, successful prevention of restenosis can result in significant health care savings as well as significant therapeutic benefits.

Monocyte chemoattractant protein 1 (MCP-1, CCL2) is used to leukocytes, especially monocytes, to the site of inflammation
Belongs to a family of potent chemotactic cytokines (CC chemokines) that regulate macrophage and T cell traffic (Charo, IF and Taubman, MB (2004) Circ. Res. 95, 85
8-866). In addition to its role, convincing evidence, for example in vascular disease, indicates the role of MCP-1 in Alzheimer's disease (AD) (Xia, MQ and Hyman, BT (1999) J Neurov
irol. 5, 32-41). Presence of MCP-1 in senile plaques and in reactive microglia, CNS
Resident macrophages were observed in the brain of patients suffering from AD (Ishizuka,
(1997) Psychiatry Clin. Neurosci. 51, 135-138). Stimulation of monocytes and microglia with amyloid-β protein (Aβ) induces chemokine secretion in vitro (Meda, L. et al. (1996) J Immunol 157, 1213-1218; Szczepanik, AM et al. (2001) J Neuroimmunol. 113, 49-62), Intraventricular injection of Aβ _(1-42) into mouse hippocampus significantly increases MCP-1 in vivo. Moreover, Aβ deposition attracts and activates microglial cells, causing them to produce inflammatory mediators such as MCP-1, which in turn induce further chemotaxis, activation, and tissue damage. To cause feedback. At the site of Aβ deposition, activated microglia also phagocytose Aβ peptide,
Cause amplification of activation (Rogers, J. and Lue, LF (2001) Neurochem. Int. 39, 33
3-340).

Examination of chemokine expression in a 3xTg mouse model for AD revealed that neuronal inflammation preceded plaque formation and that MCP-1 was upregulated 11-fold. Furthermore, up-regulation of MCP-1 appears to correlate with the first occurrence of intracellular Aβ deposition (Janelsins, MC et al. (2005) J Neuroinflammation. 2, 23).
. Crosses between the MCP-1 overexpressing mouse model and the Tg2575 mouse model for AD show an increase in microglia accumulation around Aβ deposits, which is a single transgenic Tg2576
Compared to littermates, it was accompanied by an increase in the amount of scattered plaque (Yamamoto, M. et al. (2005
) Am. J Pathol. 166, 1475-1485).

MCP-1 levels are increased in the CSF of AD patients and patients with mild cognitive impairment (MCI) (Galimberti, D. et al. (2006) Arch. Neurol. 63, 538-543). Furthermore, MCP-1 shows increased levels in the serum of MCI and early AD patients (Clerici, F. et al. (2006
) Neurobiol. Aging 27, 1763-1768).

(Definition)
(Enzyme inhibitors, especially QC inhibitors)
Reversible enzyme inhibitors: include competitive inhibitors, non-competitive reversible inhibitors, slow or tihgt inhibitors, transition state analogs, and multi-substrate analogs.

Competitive inhibitors are
i) non-covalent interaction with the enzyme,
ii) competition with the substrate for the enzyme active site,
Indicates.

The main mechanism of action of reversible enzyme inhibitors and the definition of dissociation constants can be visualized as follows:

Formation of the enzyme inhibitor [EI] complex prevents substrate binding, and thus the reaction cannot proceed to normal physiological products (P). A higher inhibitor concentration [I] results in a higher [EI] and leaves less free enzyme to which the substrate can bind.

Noncompetitive reversible inhibitor
i) Bind to sites other than the active site (allosteric binding site)
ii) causing a conformational change in the enzyme that reduces or stops catalytic activity.

Slow binding or tight binding inhibitor
i) a competitive inhibitor in which the equilibrium between the inhibitor and the enzyme is slowly achieved;
ii) probably due to conformational changes that must occur in the enzyme or inhibitor (k _on is slow)
a) Usually a transition state analogue
b) Effective at the same concentration as the enzyme concentration (KD value of nM or less)
c) This kind of inhibitor is “almost” irreversible because the k _off value is very low.

Transition state analogs Competitive inhibitors that mimic the transition state of enzyme-catalyzed reactions. Thus, enzyme catalysis is caused by a decrease in the energy of the transition state, and thus transition state binding is selected over substrate binding.

Multi-substrate analog
For reactions involving more than one substrate, competitive inhibitors, or transition state analogs that contain structural features resembling more than one substrate can be designed.

(Irreversible enzyme inhibitor): drive the unbound enzyme and the equilibrium between the inhibitor and the enzyme inhibitor complex (E + I <---> EI) completely to the EI side by covalent bond (~ 100 kcal / mol),
Causes irreversible inhibition.

Affinity-labeled agent Active site directed irreversible inhibitors (competitive irreversible inhibitors) are recognized by enzymes (reversible, specific binding), followed by covalent bond formation, and
i) structurally similar to a substrate, transition state, or product and capable of specifically interacting between the drug and the target enzyme
ii) It contains a reactive functional group (eg, a nucleophile, —COCH ₂ Br) and can form a covalent bond.

The reaction scheme below describes an active site directed reagent with its target enzyme, where _KD is
The dissociation constant and k _inactivation is the rate of covalent bond formation.

Mechanism-based enzyme inactivators (also called suicide inhibitors) are active site binding agents that bind to an enzyme active site where they are transformed into a reactive form (activated) by the catalytic ability of the enzyme. Directional reagent (non-reactive). Once activated, a covalent bond is formed between the inhibitor and the enzyme.

The reaction scheme below shows the mechanism of action of an enzyme deactivator based on the mechanism, where
_The K _D is the dissociation complex, k ₂ is the once rate of activation of the inhibitor bound to the enzyme, k ₃ is (products from enzyme activated inhibitor P is still The rate of dissociation (which can be reactive) and k ₄ is the rate of covalent bond formation between the activated inhibitor and the enzyme.

Inactivation (covalent bond formation, k ₄ ) must occur before dissociation (k ₃ ), otherwise the reactive inhibitor is released into the environment. Partition ratio, k ₃ / k ₄ : The ratio of released product to inactivation should be minimized for efficient inactivation of the system and minimal unwanted side reactions.

  Large partition ratios (choose dissociation) cause non-specific reactions.

(Uncompetitive enzyme inhibitor): As a definition of uncompetitive inhibitor (inhibitor that binds only to the ES complex), the following equilibrium equation can be assumed:

The ES complex separates the substrate with the same dissociation constant as Ks, but the ESI complex does not separate it (ie has a Ks value equal to zero). The Km of Michaelis-Menten enzyme is expected to be reduced. Increasing the substrate concentration causes an increase in ESI concentration (complex that cannot progress to the reaction product), and thus inhibition cannot be removed.

  Competitive enzyme inhibitors are preferred in the present invention.

  Competitive reversible enzyme inhibitors are most preferred.

The terms “K _i ”, or “K _I ”, and “K _D ” are binding constants that describe the binding of an inhibitor to an enzyme and subsequent release. Another measure is the “IC ₅₀ ” value, which reflects the inhibitor concentration and produces 50% enzyme activity at a given substrate concentration.

Highly dispersed silica, silicic acid), sugars (eg, crude sugar, lactose, and dextrose);
Emulsifiers such as nonionic and anionic emulsifiers (eg, polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, alkyl sulfonates, and aryl sulfonates), dispersants (eg, lignin, sulfite cooking liquor, Methylcellulose, starch, and polyvinylpyrrolidone), and lubricants (eg, magnesium stearate, talc, stearic acid, and sodium lauryl sulfate), and optionally seasonings.

Administration may be carried out in the usual manner, preferably enterally or parenterally, in particular orally. For enteral administration, tablets refer to additional additives such as sodium citrate, calcium carbonate, and calcium phosphate, along with various additives such as starch, preferably potato starch, gelatin and the like, in addition to the carriers mentioned. In addition to the above-mentioned carrier, it may be contained. Furthermore, lubricants such as magnesium stearate, sodium lauryl sulfate, and talc can be used simultaneously for tableting. In the case of aqueous suspensions and / or elixirs intended for oral administration, various taste modifiers or colorants can be added to the active ingredient in addition to the excipients described above.

For parenteral administration, a solution of the active ingredient can be used using a suitable liquid carrier. In general, for intravenous administration, approximately 0.01-2.0 mg / k per day to obtain effective results
g, preferably about 0.01 to 1.0 mg / kg body weight has been found to be advantageous, and for enteral administration the dosage should be about 0.01 to 2 mg / kg per day. The body weight is preferably about 0.01 to 1 mg / kg.

Nevertheless, in some cases, depending on the body weight of the experimental animal or patient, or by the type of route of administration, but based on the species of animal and its individual response to the drug, or on the interval at which the administration is performed It may be necessary to deviate from the stated amounts. Thus, in some cases it may be sufficient to use less than the minimum amount mentioned above, but in other cases the upper limit mentioned may have to be exceeded. If relatively large amounts are administered, it may be desirable to divide these amounts into several single doses over the day. For administration in human medicine, the same dosage tolerances are provided. The above findings apply analogously to that case.

(Reference Example 1: Preparation of human QC)
Host strain and medium Pichia pastoris strain X33 (AOX1, used for expression of human QC)
AOX2) was cultured, transformed and analyzed according to the manufacturer's instructions (Invitrogen). The media required for P. pastoris, buffered glycerol (BMGY) complex media or methanol (BMMY) complex media, and fermentation basal salt media were prepared according to the manufacturer's recommendations.

(Molecular cloning of plasmid vector encoding human QC)
All cloning procedures were performed applying standard molecular biology techniques. The vector pPICZαB (Invitrogen) was used for expression in yeast. pQE-31 vector (Qiagen
) Was used to express human QC in E. coli. Mature QC starting at codon 38
Of cDNA was fused in-frame with a plasmid encoding a 6 × histidine tag. After amplification using primers pQCyc-1 and pQCyc-2 (WO2004 / 098625) and subcloning, the fragment was inserted into an expression vector using SphI and HindIII restriction sites.

(P. pastoris transformation and mini-scale expression)
Plasmid DNA was amplified in E. coli JM109 and purified according to manufacturer's (Qiagen) recommendations. In the expression plasmid used (pPICZαB), three restriction sites are provided for linearization. Since SacI and BstXI cleaved the cDNA in QC, PmeI was selected for linearization. 20-30 μg plasmid DNA was linearized with PmeI, precipitated with ethanol and dissolved in sterile deionized water. Then 10 μg of DNA was added to the manufacturer's instructions (Bior
ad) and applied for transformation of competent P. pastoris cells by electroporation. Selection was performed using plates containing 150 μg / ml Zeocin. Hundreds of transformants were obtained by one transformation using the linearized plasmid.

To test recombinant yeast clones for QC expression, recombinants contain 2 ml of BMGY
Incubate for 24 hours in 0 ml conical tubes. The yeast was then centrifuged and resuspended in 2 ml BMMY containing 0.5% methanol. This concentration was maintained up to 72 hours by adding methanol every 24 hours. Thereafter, the QC activity in the supernatant was determined. The presence of the fusion protein was confirmed by Western blot analysis using an antibody directed against a 6 × histidine tag (Qiagen). Clones that showed the highest QC activity were selected for further experiments and fermentation.

(Large scale expression in fermenter)
QC expression was performed in a 5 l reactor (Biostat B, B. Braun biotech), essentially as described in “Pichia Fermentation Process Guidelines” (Invitrogen). Briefly, cells were cultured in a fermentation basal salt medium supplemented with trace salts and glycerol as the sole carbon source (pH 5.5). Large amounts of cells accumulated during the initial batch phase of about 24 hours and the subsequent feed batch phase of about 5 hours. Once 200 g / l wet cell weight was achieved, methanol was used to induce QC expression by applying a three-step feed profile during the entire fermentation time of approximately 60 hours. Thereafter, the cells were removed from the supernatant containing QC by centrifugation at 6000 × g and 4 ° C. for 15 minutes. The pH was adjusted to 6.8 by addition of NaOH and the resulting cloudy solution was centrifuged again at 37000 × g, 4 ° C. for 40 minutes. If turbidity continues, the cellulose membrane (

Acclimatization and health procedures Upon arrival, all animals were examined for unhealth. Animals were acclimated for a period of at least 5 days prior to dosing. During this time, animals were identified by their cage label. Veterinary examinations were performed before the start of any experimental procedure to confirm their suitability for the study.

Experimental design The study was conducted over 2 days (5 animals from each treatment group on each day).
. Food and water were available as appropriate except when animals were removed from the home cage for study procedures. Each animal uses a specific dose volume of 2 mL / kg as a slow bolus dose, at low, medium and high doses (Table 2), 3.5 hours and 0.5 hours before LPS administration, We received two single intravenous doses of vehicle or QC inhibitor 1- (3- (1H-imidazol-1-yl) propyl) -3- (3,4-dimethoxyphenyl) thiourea.

Induction of peritonitis induced by thioglycolate For the induction of peritonitis, mice were injected intraperitoneally (ip) with 25 ml / kg body weight of sterile 8% (w / v) thioglycolate (Sigma) -Aldrich; Time: t = 0). At different time points before and after thioglycolate application, mice were injected ip with various concentrations of QC inhibitors.

The expression of the human MCP-1 variant in HEK293 is monitored by the human MCP-1 ELISA,
High levels are reached in the cell culture supernatant. According to this, MCP-1 (WT) and MCP-1 (ΔQ1) (Fig.
5C) and MCP- in the absence or presence of 10 μM 1- (3- (1H-imidazol-1-yl) propyl) -3- (3,4-dimethoxyphenyl) thiourea hydrochloride (FIG. 7A) The level between 1 (WT) does not change significantly. However, the expression of MCP-1 (ΔQ1P2) is 28 compared to MCP-1 (WT).
Reduced by%. The supernatant was collected and applied to the TransWell migration assay (see FIGS. 4, and 5C and D for this point).

TransWell chemotaxis assay Purified human MCP-1 exhibits a bell-shaped chemotaxis dose response curve when attracted, for example, monocytes are optimal at about 1-50 ng / ml. Therefore, to achieve the optimal working concentration of MCP-1 for the chemotaxis assay that attracts THP-1 monocytes, the cell culture supernatant containing the produced MCP 1 mutant was serially diluted.

After expression of MCP-1 (WT) and MCP-1 (ΔQ1), the concentration of MCP-1 mutant was not significantly different (FIG. 5C). Application of MCP-1 (WT) to the chemotaxis assay caused a chemotactic response in THP-1 cells (FIG. 5D), indicated by a high chemotaxis index. However, MCP-1 (ΔQ
1) was unable to induce THP-1 chemotaxis, suggested by a chemotaxis index of approximately 1 (FIG. 5D). These results support the previous results that N-cleaved MCP-1 is inactive. This finding is further evidenced by the inability of MCP-1 (ΔQ1P2) to induce chemotaxis of THP-1 cells (FIG. 6B). Expression of MCP-1 (WT) in HEK293 cells has no effect on the absence or presence of chemotactic cytokines (chemokines). However, application of chemokines causes significantly lower chemotaxis of THP 1 cells at 1: 3 and at 1:10 dilution (FIG. 7B). This is due to MCP-1 (WT) with 1- (3- (1H-imidazol-1-yl) propyl) -3- (3,4-dimethoxyphenyl) thiourea hydrochloride, a QC-specific inhibitor.

As a result of QC inhibitor administration, the unprotected N-terminal group is easily cleaved by DP4. N-terminal truncation then causes inactivation of human MCP-1 (FIGS. 5 and 6). MMP-1 inactivates mature MCP-1 by cleavage of the four N-terminal amino acids (pE / QPDA). The reaction is independent of the presence of the N-terminal pGlu residue. This process reflects the situation of MCP-1 inactivation in the circulation. _Resulting cleavage product MCP 1 _(5-76)
Has been shown to be present in plasma and resembles a naturally occurring CCR2 receptor antagonist. This experiment shows the finding that MMP-1 cleavage is slightly faster with the N-terminal glutamine residue (FIG. 2A: 2 hours, 4 hours vs. 2B: 2 hours, 4 hours). Furthermore, incubation of human MCP-1 with an N-terminal Gln residue (FIG. 3A) with human DP4 and human MMP-1 was performed using pGlu-MCP-1 (FIG. 3
Compared with B), it shows accelerated decomposition.

Taken together, the results show that N-terminal pGlu formation represents a protective mechanism, post-proline cleavage enzyme,
Implies to a certain extent resistance to endoproteases, for example to DP4, N-terminal degradation by aminopeptidases and as implied by the results with MMP-1. QC
Blocking N-terminal pGlu formation by application of an inhibitor causes more rapid inactivation of human MCP-1.

Analysis of vascular remodeling and promotion of atherosclerosis in ApoE3 * Leiden mice
Treatment of cuff-induced promotion of atherosclerosis in ApoE3 * Leiden mice has no effect on the total area within the outer diameter of the vascular segment (Figure 8A) and mild in the remaining lumen Although an increase can be observed, there was no statistically significant effect on the remaining lumens (FIG. 8B). However, hydrochloric acid 1- (3- (1H-imidazol-1-yl) propyl) -3- (3,4-

And a 45% reduction in the area of neointima formation (FIG. 9B). Both values are statistically significant. Furthermore, the inhibitor decreased the media area (Figure 10A) and the intima / media ratio (Figure 10B), but the decrease in the intima / media ratio was statistically significant. (P <0.102).

MCP-1 expression is 1- (3- (1H-imidazol-1-yl) propyl hydrochloride) -3- (3, 2 days after surgery, which is the moment of highest rise in MCP-1 expression in the model used There was a decrease in the vascular segment of mice treated with 4-dimethoxyphenyl) thiourea (FIGS. 12, 13A, 14A). These results indicate that 1- (3- (1H-imidazol-1-yl) propyl) -3- (3,4-dimethoxyphenyl) thiourea hydrochloride is administered early after vascular injury in the lesion. The media of the vascular wall segment,
And a decrease in MCP-1 expression can be detected both in the inner membrane (ie, inside the inner elastic lamina). Analysis of the relative area of the cross section positive for MCP-1 reduced 52% (P = 0.01) of MCP 1 expression in the media and 36% (P = 0.001) in the intima (Figure 14A) Became clear.

QC inhibitor 1- (3- (1H-imidazol-1-yl) propyl) -3- (3,4, a QC inhibitor for the production of N-terminal pGlu-residue and its subsequent effect on proteolytic stability To further illustrate the effect of -dimethoxyphenyl) thiourea, human MCP-1 with N-terminal glutamine (FIG. 17A) or pyroglutamic acid (FIG. 17B) was incubated with DP4. N-terminal pGl
u-formation was achieved by preincubation of human QC and precursor, reflecting the physiological maturation process. As expected, in the absence of preincubation with human QC, MCP-1
Is sensitive to DP4 cleavage (FIG. 17A). In contrast, preincubation with human QC causes the formation of an N-terminal pGlu-residue and thus its protection against DP4 cleavage (FIG. 17B). In addition, QC inhibitor 1- (3- (1H-imidazol-1-yl) propyl) -3 hydrochloride
Pre-incubation of human MCP-1 with human QC in the presence of-(3,4-dimethoxyphenyl) thiourea results in inhibition of QC and thus prevention of pGlu-MCP-1 formation. Hydrochloric acid 1-

). Thus, inhibition of QC causes destabilization of the N-terminus of MCP-1 in vitro and in vivo.

Similar to N-terminal cleavage of human MCP-1 by DP4, recombinant human aminopeptidase P and Gln ¹ -M
Incubation of CP-1 causes unprotected N-terminal truncation. As a result, aminopeptidase P cleaves the N-terminal amino acid between Gln ¹ and Pro ² to release the N-terminal glutaminyl residue (FIG. 16A). However, preincubation of Gln ¹ -MCP-1 with human QC results in the formation of an N-terminal pGlu-residue, thus resulting in protection against aminopeptidase P cleavage (FIG. 16B). Thus, the formation of the N-terminal pGlu-residue is also a protective mechanism against aminopeptidase P cleavage and possibly against the cleavage of all other proline-specific aminopeptidases. For further studies on the proteolytic stability of human MCP-1, the data obtained by incubation of purified protease with MCP-1 was verified by incubation of human serum with human MCP-1. Human serum and human Gln
Incubation of ^1- MCP- ¹ involves cleavage of the N-terminus of the substrate and the first two amino acids (Gln ¹ Pro
² ) indicates release. In addition, QC activity in plasma competes with N-terminal proteolysis and MCP-
Stabilize 1 and end with a final ratio of approximately 60% truncated Asp ³ -MCP-1 and 40% full length pGlu ¹ -MCP-1 (FIG. 18A). Furthermore, by preincubation of human QC and human MCP-1, N-terminal pG
It causes the formation of lu-residues and thus the stabilization of human MCP-1. No degradation of pGlu ¹ -MCP-1 was observed at least for the selected time frame and serum dilutions (FIG. 18B). In addition, incubation of MCP-1 in serum in the presence of 9.6 μM DP4-inhibitor isoleucyl-Thiyzolidide also prevented N-terminal degradation, which means that MCP-1 is DP4 or DP4 in human serum It is proved that it is degraded by a similar activity (Figure 18C).

Proteolysis of human MCP-2, MCP-3, and MCP-4 Similar to the N-terminal degradation of human MCP-1, other human MCPs for N-terminal cleavage by DP4, namely MCP-2, MCP-3, and The sensitivity of MCP-4 was investigated. As previously observed for MCP-1, the N-terminal pGlu-residue is linked by DP4 to MCP-2 (Figure 19B), MCP-3 (Figure 20B), and MCP-4 (
Figure 21 B) is protected from proteolysis. However, uncyclized mutants starting with N-terminal glutamine are Gln ¹ -MCP-2 (FIG. 19A), Gln ¹ -MCP-3 (FIG. 20A), and Gln ¹ -MCP-4 (FIG. 19).
As shown for 21 A), it is easily cleaved by DP4. Thus, the N-terminal pGlu-residue stabilizes all MCPs against cleavage by aminopeptidases such as DP4. Therefore,
The proposed concept for reducing QC activity in vivo to promote turnover, and chemotaxis and receptor activation applies to all members of the MCP-family.

Chemotaxis performance of different N-terminal mutants of human MCP-1, MCP-2, MCP-3, MCP-4 Investigating the effect of different N-terminal mutants of MCP-1 on the ability to attract human THP-1 monocytes Gln ¹ -MCP-1, pGlu ¹ -MCP-1, aminopeptidase P cleavage product Pro ² -MCP-1, DP4 cleavage product Asp ³ -MCP-1, and MMP-1 cleavage product Ile ⁵ -MCP -1 was tested in an in vitro chemotaxis assay. N
Full length MCP-1 with terminal glutaminyl, or pyroglutamyl-residue, 50 ng / ml to 100 ng / ml
Was found to be as powerful in attracting THP-1 monocytes.
In contrast, cleavage of MCP-1 by aminopeptidase P (Pro ² -MCP-1) and DP4 (Asp ³ -MCP-1) causes a loss of the ability of the respective mutants. Changing the dose response curve to a higher concentration requires eliciting a maximal response, which corresponds to inactivation of MCP-1 by N-terminal truncation. MMP-1 cleavage product (Ile ⁵ -MCP-1) has a maximum equivalent to Glu ¹ -MCP-1 and pGlu ¹ -MCP-1 between 50 ng / ml and 100 ng / ml, but full length MCP Compared to -1, the amount of cells migrating to this mutant (ie, chemotaxis performance) is very low (Figure 22).

To further investigate the role of QC in stabilizing MCP-1 and its effect on THP-1 monocyte migration, Gln ¹ -MCP-1 was incubated with human DP4. In parallel samples, MCP-1
Pre-incubated with human QC prior to DP4 application. As expected, the resulting dose response curve is 5
Implying the proteolytic stability of pGlu ¹ -MCP-1 as reflected by the maximum response at 0-100 ng / ml. In contrast, in the absence of QC, Gln ¹ -MCP-1 is cleaved by DP4, which results in a higher MCP-1 concentration (500-1000 ng / ml) required to elicit a maximal response Causes a change in the dose-response curve. In addition, QC and the QC inhibitor 1- (HCl, as observed by the change in dose response curve to higher MCP-1 concentrations compared to pGlu ¹ -MCP-1 (FIG. 23). Pre-incubation of 3- (1H-imidazol-1-yl) propyl) -3- (3,4-dimethoxyphenyl) thiourea with Gln ¹ -MCP-1 prevents pGlu- formation and thus prevents DP4 cleavage It gives a peptide that is fragile. Thus, inhibition of QC causes MCP-1 N-terminal destabilization via degradation by DP4 and thus its inactivation with respect to monocyte chemotaxis activity.

In addition, the ability of MCP-2, MCP-3, and MCP-4 with N-terminal glutamine or pyroglutamic acid to attract human THP-1 monocytes was investigated. Like MCP-1, pGlu-formation at the N-terminus of MCP-2 and MCP-3 has no effect on performance compared to the respective glutamine-precursor. However, for MCP-4, pGlu-formation slightly increases the ability of the peptide (
Figure 24). However, because glutaminyl-precursor is cleaved by DP4 (Figure 19, 20, 21)
Also, the ability of N-cleaved DP4 cleavage products of MCP-2, MCP-3, and MCP-4 was investigated using a chemotaxis assay. For all three variants, cleavage by two amino acids causes partial inactivation of chemokines (Figure 25). Thus, pGlu- formation at the N-terminus of all known MCPs not only protects against N-terminal truncation, but also protects against loss of chemotaxis performance. Thus, the proposed approach to reduce the activity of MCP-1 by inhibiting N-terminal maturation applies to all members of the MCP family in humans.

Application of QC inhibitors to a model of LPS-induced sepsis in rats General 1- (3- (1H-imidazol-1-yl) propyl) -3- (3,4-dimethoxyphenyl) thiourea hydrochloride In order to investigate anti-inflammatory properties, inhibitors were applied to a model of LPS-induced sepsis in rats. Cytokine TNFα as a marker that the inflammatory response has begun
The level of was determined according to QC inhibitor treatment. As illustrated in FIG. 26, the application of 1- (3- (1H-imidazol-1-yl) propyl) -3- (3,4-dimethoxyphenyl) thiourea hydrochloride is low dose (5 mg / kg) Causes a dose-dependent decrease in TNFα levels ranging from 1 to intermediate doses (20 mg / kg). In addition, the highest dose (80 mg / kg) also reduced TNFα- levels in plasma, but a slight increase was observed compared to the intermediate dose. Thus, QC inhibitor application can significantly reduce the inflammatory response shown herein, taking TNFα as an example. In experiments, the effects of QC inhibitors are highly specific due to MCP N-terminal destabilization, but this inactivation of chemokines also affects other inflammatory parameters such as TNFα. It shows having. Thus, suppression of other pro-inflammatory cytokines is a further result of the proposed concept that destabilizes MCP. This approach is therefore suitable for developing pharmacotherapy for different inflammatory disorders that alter the degree of MCP action.

Application of QC inhibitors to a model of thioglycolate-induced peritonitis in mice To further investigate the effects of QC inhibitor administration on immune cell migration in vivo
1- (3- (1H-imidazol-1-yl) propyl) -3- (3,4-dimethoxyphenyl) thiourea was applied to a model of murine thioglycolate-induced peritonitis. The cellular composition of the peritoneal dialysate was determined with particular emphasis on infiltrating monocytes at 4 and 24 hours after thioglycolic acid induction. As shown in FIG. 27, the QC inhibitor 1- (3- (1H-imidazol-1-yl) propyl) -3- (3,4-dimethoxyphenyl) thiourea was dose-dependent after 4 hours. The number of monocytes that infiltrate the peritoneum was reduced. In addition, the presence of Moma2-positive monocytes / macrophages was assessed 24 hours after thioglycolate application. As illustrated in FIG. 28, the QC inhibitor 1- (3- (1H
-Imidazol-1-yl) propyl) -3- (3,4-dimethoxyphenyl) thiourea is significantly
The number of a2-positive cells was also reduced. Thus, inhibition of QC destabilizes the N-terminus of MCP in vivo.

This experiment demonstrates the applicability of MCP destabilization by QC inhibition to observe therapeutic effects. Some inflammatory disorders, such as but not limited to atherosclerosis, and monocyte recruitment, a common feature of restenosis, are suppressed. Thus, this experiment provides a method for characterizing QC inhibitors for their applicability in different inflammatory disorders.
